Abstract

The aim of this study is evaluating of accuracy of FAO methods for qualitative land suitability of barley in Damghan plain and make easy farmers’ choice for planting the best crop in the land. This study was carried out in an area including 5400 ha in the southern part of Damghan city in the form of semi-detailed surveying level. The results showed that the climatic characteristics of the region were suitable for irrigated barley plantation. Lack of suitable water for irrigation, soil salinity and alkalinity, some soil physics properties and poor soil fertility were the most serious problems influencing yield and quality of barley. Assessment results showed Square Root method (SL) and Simple limitation method (SR) had close correlation. This study suggested to use SL method and SR for evaluation of the land suitability. According to the obtained results of SR and SL methods cultivation of barely with moderately and marginally suitable class are recommended. Proper land management practices, leaching, drainage, land preparation crop rotation, specific irrigation methods and using resistant crop help to increase crop yield in this area.
